Synthetic pyrrhotites Fe(1-x)S, synthesized at various compositions and temperatures, show the presence of two new superstructures based on the hexagonal subcell of the NiAs type (axes A and C): one, in the range 1-x=0.89 to 0.93, has a = 90A and c = 3C; the other, in the range 1 -x = 0.935 to 0.975, has a = 2A but c irrationally related to C, varying with composition.
在不同组成和温度下合成的人工非晶质硫铁矿 Fe(1-x)S 表现出基于 NiAs 型（轴 A 和 C）的六方亚晶格的两种新超结构：一种在 1-x=0.89 到 0.93 范围内，a = 90A，c = 3C；另一种在 1-x=0.935 到 0.975 范围内，a = 2A，但 c 与 C 呈无理相关，随组成而变化。
